LOOMIS MANN, OF IOVNIA, MICHIGAN.

AIMPROVED MACHINE FOR MAKING EAVES-TROUGHS.`

Specification forming part of Letters Patent No. 27,916. dated April 1,7, 1360- To aJZZ whom t may concern,.-

Be it known that I, LOOMIS MANN, of Ionia, in the county of Ionia, in the State of Michigan, have invented a new and uset'ul Machine for Manufacturing Tin Eaves-Troughs; and I do hereby declare that the following is a full, clear, and exact description of the construetion and operation of the same, reference being had to the annexed drawings, making a part of this specification. in which Figure lis aperspective view; Fig. 2, alongitudinal elevation; and Fig. 3 shows a faceplate representing the scallops on the front edge to correspond with scallops on movable bar D, which scallops are made for the purpose oi' letting the soldering-iron pass to the edge ot' the tin, so as to solder the entire length ofthe seam.

The metallic restA is used for holding the bed-piece Blevel while inserting the tin'. The bed-piece B has a groovev on top` into which the tin isinserted. ThefaceplateC is moved by eccentric Fever the groove to hold or coniine the tin in the groove. Movable bar D is used to press the tin to the roller H, aud to form the trough, as also to hold the same untilsoldered. The eccentrics E E at each end of movable bar D are used to press movable bar D down upon the tin. The coil-springs G G, at each end ot' movable bar D, are used to raise the said bar, and to hold the same from the roller H While the troughis removed and more tin inserted.

Directions for using: First, raise metallic rest A upright or perpendicular 5 second, place bed-piece B on rest A; third, move faceplate C back by turning eccentric F to the left hand; fourth, move movable bar D over faeeplate C, fifth, turn eceentrics E E over and out-one to the right, the other left; sixth, i11- sert six sheets of tin into groove in bed-piece B 5 seventh, move face-plate C over the head on tin by turning the eccentric F to the right hand, eighth, turn eccentrics E E over and in toward operator; ninth, take the handle on bed-piece B in the left hand and the handle on movable bar D in the right hand, then force the movable bar D over from the operator until the edge ofthe tin is seen through the scallops; tenth, move the rest A toward the left to a horizontal position, lea-ving roller andtin in a rolling condition for soldering.

The peculiar advantages of my machine over all others now in use are, first, in the facility ot' operating it, arising mainly from the arrangement ofthe roller H and bar D for operating by levers from their midlength. so that the workman does not change his position from the time of putting the prepared tin into the machine until it is formed, soldered, and taken out; and, secondly, by notching the edges of the face-plate C and the bar D, which retain the trough on the roller H, Where they cross the lap of the plates, by which the Workman is enabled to solder the entire length of the seam while on the former, thus avoiding the necessity ofhandling to iiuish the work after taking it out ofthe machine, and the liability of straining it out of line by such procedure.

Having thus described my invention,whatl claim as new, and desire to secure by Letters Patent, is-

l. The wing or bed piece B and clampingplate C, rigidly attached to the roller H, forming a lever thereto, operating in combination with the movablebar D, in the manner and for the purposes set forth.

2. Notching the edges of the bar D and clamping-plate G where they cross the lap ot' the plates to admit of their being soldered from edge to edge While in the machine, substantially as specified.
